Patent number: 12265102Abstract: A non-contact electric potential meter system to determine voltage between an AC conductor and a reference potential without direct electrical contact to the conductor. A housing provides a shielded measurement region that excludes other conductors and holds power supply means; an AC voltage sensing mechanism includes a conductive sense plate and an electrical connection to the reference potential. Waveform-sensing electronic circuitry obtains an AC voltage waveform induced by capacitive coupling between the conductor and the conductive sense plate. Capacitance-determining electronic circuitry obtains a scaling factor based on the coupling capacitance formed between the conductor and the conductive sense plate. Signal processing electronic circuitry uses the AC voltage waveform and the coupling capacitance-based scaling factor to obtain the voltage between the conductor and the reference potential.Type: GrantFiled: March 28, 2023Date of Patent: April 1, 2025Assignee: 4QUADRANT NETWORKS INC.Inventors: Prabal Dutta, Michael C.

Publication number: 20180003739Abstract: An improved energy meter is presented that achieves a vastly smaller form factor than prior systems. The energy meter occupies an unobtrusive and essentially two-dimensional volume, 1?×1?× 1/16?, and meters loads plugged through it and into an outlet. Despite its small size, the energy meter is a wireless true power meter, capable of metering real, reactive, and apparent power at kHz frequencies, aggregating these measurements into cumulative energy, and transmitting these data several times per second using a Bluetooth Low Energy (BLE) radio to a nearby smart phone or gateway. At a cost of $11 in modest quantities of 1,000 units, the energy meter is the smallest and lowest cost AC plug-load meter with 1.13% accuracy over a 2-1200 W range for unity power factor loads, and slightly worse for non-linear and reactive loads. This small form factor, coupled with easy access to and transport of the meter data, enables new applications.Type: ApplicationFiled: June 30, 2017Publication date: January 4, 2018Inventors: Samuel DEBRUIN, Branden GHENA, Prabal DUTTA

Publication number: 20130229274Abstract: One aspect of the invention provides a theft detection system including one or more tag nodes configured to detect movement and transmit a beacon message and one or more anchor nodes configured to receive the beacon message from the one or more tag nodes and alert a third party of the beacon message. Another aspect of the invention provides a theft detection node including a power source, a motion detector, a transmitter, and a microcontroller in communication with the power source, the motion detector, and the transmitter. The microcontroller is configured to determine whether the node is being transported and if the node is being transported, instructing the transmitter to transmit a beacon message. Another aspect of the invention provides a theft detection method including detecting motion in a motor vehicle and transmitting a beacon message to an anchor node.Type: ApplicationFiled: February 25, 2013Publication date: September 5, 2013Applicants: University of Memphis Research Foundation, The Regents of the University of California, The Ohio State UniversityInventors: Santosh Kumar, Prasun Sinha, Kurt Plarre, Somnath Mitra, Zizhan Zheng, Santanu Guha, Animikh Ghosh, Prabal Dutta, Bhagavathy Krishna
